Specification of Letters Patent.

Patented May 7, 1907.

Application filed January 26, 1906. Serial No. 298.023.

To all whom it may concern:

Be it known that I, DENNIs T. Icon, a citizen of the United States, residing at Spring field, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Machines for Forming and Wrapping Confections and other Articles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for forming and wrap ing confections and other articles, and is in tlie general nature of an improvement upon the machine set forth in an application filed by me March 26, 1903,,Ser. No. 149,681, the present machine also en1 bodying some of the features disclosed in an application filed by me December 23, 1903, Ser. No. 186,282.

The primary object of my present invention is to provide an automatic mechanism which will handle the candy from the batch ,ularly point out in the'claims.

without the assistance of manual labor, and

which will form and wrap the confections automatically and deliver them completely formed and wrapped.

Among other objects of the present invention, the main object is to increase the output of the machine, increasing the speed and accuracy with which the various parts operate, with a special view to certainty as well as celerity of operation, so that the machine may be operated at very high speed without danger of'cloggin or failing to properly perform its various inctions. Y

The invention has for its further object to. provide certain improvements in the mechanisms are rendered more eflicient, accurate and ra id in operation.

To t iese and other ends my invention consists in certain novel features which I will now proceed to describe, and will then partic- In the accompanying drawings, Figure 1 is a plan view of a machine embodying my invention in one form; Fig. 2 is a front elevation of the same; Fig. 3 is a rear elevation;

In describing the particular embodiment of my invention chosen for purposes of illustration, I shall first describe the candyfeeding and confection-forming mechanisms, by

which the candy is drawn fro n the batch, formed into confections, and delivered to the wrapping mechanism. I will next describe the paperieeding and cutting mechanism, by means of which the web of paper is drawn from the roll and severed into sheets to form the wrappers, and by which these wrappers are delivered to the. wrapping mechanism to be wrapped around the confections. I will then describe the wrapping mechanism, by means of which the wrappers are wrapped around the confections, being folded around the same at their body portions, while their projectingiends are twisted to complete the package.

The machine as a whole is supported upon a frame indicated by the reference numeral 1,

and provided with a driving pulley 4, to receive admit to drive the machine from any suitable source of power. The driving pulley may be connected with and disconnected from the shaft 2, in order to start or stop the machine, by means of a suitable clutch 5, controlled by an arm 6, mounted on one end of a rock shaft 7, located at the back of the machine, the other end of the rock shaft carrying a hand lever 8, which extends across the machine to the front thereof to a point Within convenient reach of the operator.

Candy-feeding at confection-forming machine.This mechanism comprises a suitable support for the batch of candy, means for antomatically drawing the candy from the batch and feeding it forward to the forming rolls, at the same time forming it into a bar having a diameter such as to properly feed through and supply the forming rolls. The

said mechanism further comprises forming rolls which give the confection its proper form and mass, cooperating to that end with a cutter which at predetermined intervals severs the bar fed from the forming rolls, thereby dividing the'same into confections containing the predetermined amount of candy and having the general form desired. After the confections are thus formed, they are delivered to a tempering conveyer, which carries them along separately, exposing them to the atmosphere for a length of time sufi'i cient to permit themto shrink and set somewhat. The shrinking and setting conveyer delivers the confections to a second conveyer, by means of which they are carried to the sizing rolls, which prevent excessive width of the confections, and from the sizing rolls another conveyer carries off the confections and delivers them to the wrapping mechanism.

The main frame 1 comprises uprights 9,

which support a base plate or table 10, on which are mounted the feeding rolls and batch support. In the present instance I have shown three pairs of feeding rolls, but their number may be varied. Each pair is mounted in a suitable housing 11, supported on the base plate 10, and the housing 11 of the first pair of rolls has adjacent to it the batch support 12, which may be of any suit able construction.

The form of batch support which I prefer is one which I have devised, and which is illustrated more particularly in Figs. 48 to 52 of the drawings, inclusive, the same being in the form of a diminisher, which supports and holds the batch and at the same time gradually works the same and gives it an elongated tapering form, of a diminishing diameter, just as the batch is ordinarily manipulated by the hands of the operator when this work is manually done. An advantage of considerable importance in connection with this diesaseo minisher is that it .enables me to handlea larger batch, and at the same time employ a smaller number of feeding and drawing rolls for-drawing the candy from the batch and delivering it in a stick or bar of the desired diameter at the point where it is to be further worked.

Referring now more particularly to the detailed construction of this device, it will be seen that it is mounted upon a bracket 362, and stands at an inclination to the horizontal sufficient to cause the candy to tend to feed outward from the same by gravity. The body of the support or diminisher consists of a receptacle of conical form, open "at both ends, i

the larger end, which is elevated, being the receiving end, and thesmaller end, which is depressed, beingthe discharge end or outlet. The body of this receptacle is composed of a plurality of sections or staves, which are moved toward and from the axial central line of the receptacle while always remaining in contact with each other so as to maintain a closed wall surrounding the batch of candy. To effect this result some of the sections or staves are made of resilient material. In

practice, I prefer the construction shown, in

which the body of the receptacle is composed of four sections orstaves, these sections being arranged in two pairs, the two sections of each pair being similar and arranged diametrically opposite each other. In this construction there are two sections 363, preferably of a material of a thickness sufficient to render them substantially rigid, and two sections 364, of a resilient material such as thin sheet steel, each section 364 lying between two of the sections 363, with its beveled mar gins overlapping and always bearing against the inner faces of the sections 363. The rece tacle thus constituted is supported in the The rigid sections 363 f6 owing manner.

have connected to their lower depressed ends of the arm 371.

arms 365, which extend downward and for ward and are pivoted upon a stud 366, mounted in a sleeve or hub 367 formed on the bracket 362. The outer end of the bracket 362 supports a substantially rectangular frame 368, in which are supported four shafts 369, arranged at right angles to each other in parallel pairs, two of'said shafts being located respectively above and below the larger end of thereceptacle, while the other two are located at the sides thereof. These shafts are .all connected by bevel gears 370, so as to rotate in unison. Each shaft is provided with a central arm 371, the free end of which is pivotally and slidingly connected to one of the sections of the rece' tacle body. This connection is preferably effected in the manner shown, by providing 4 each section with a lug 372, having a slot 373 to receive a pin 374, supported in the bifurcated free end The resilient sections 364, being of relatively thin material, are centrally strengthened by having secured to them a longitudinally extending bar 375, preferably T -shaped in cross section, as shown, and it is to these bars that the lugs 372 of the resilient sections are secured. The lugs 372 of the rigid sections 362 have bases 376, by means of which they are directly riveted to the relatively fixed bodies of the sections 363; It will be seen that the sections 363 are thus supported and guided at both ends, their lower ends being supported by the pivoted arms 365 and their upper ends by the arms 3711' The thin resilient sections 364 are supported at their upper ends by the arms 371, while their lower ends are supported by toggle links 377, arranged in pairs above and below the receptacle. These links have their inner adjacent ends pivoted to each other and to the smaller ends of the sections 364, as indicated-at 378. The outer "ends of said links are pivoted, as indicated at 379, to arms 380, which move in unison with the sections 363. In the present. instance, I have shown these arms 380 as forming extensions of the arms 365, but they may obviously be made separate therefronr.

As an additional means for supporting and guiding the resilient sections 364, which are somewhat loosely supported at their ends, I

on the bracket 362, and provided with guides or slideways 382, arranged respectively above and below the receptacle. The resilient sections 364 are provided with guiding projections or slides 383, which fit within the slideways 382 so as to support the sections against lateral displacement, while at the same time leaving them free to rock some- .what in a plane longitudinally of the device to render them self adjusting.- Motion is imparted to the entire device by means of an arm 384, secured to one of the shafts 369. This arm is vibrated by means of a link or connecting rod 385, pivoted at its upper end to the free end of the arm 384, while its lower end is, connected to the crank 48 on the main shaft 2, hereinafter referred to. It will be understood that the normal curvature of the resilient sections 364 is such that when the receptacle is expanded to its greatest diameter, as shown in the drawings, the longitudinal edges of said resilient sections press against the adjacent faces of the intermediate sections. This being the case, as the sections move inward toward each other, the resilient sections will always have their said edges pressed against the inner faces of the adjacent sections, the same being true when the sec tions are moving outward again. Thus, a receptacle is provided having a'constantly continuous inclosing wall, which receptacle is conical in shape, diminishing in diameter toward its discharge end, said diameter constantly diminishing and increasing as the sections move toward and from the central provide'a support or standard 381, mounted 9
